SHIKAZO YAMAMOTO, OF LOS ANGELES, CALIFORNIA.

REINFORCED BROOM.

Application filed February 24, 1919.

To all whom it may concern:

Be it known that I, SHIKAZO YAMAMo'ro, a subject of the Emperor of Japan, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Reinforced Brooms, of which the following is a specification.

This invention has relation to improvements in brooms, and has for its objects the provision of means for preserving the original form of the broom, and increasing the term of usefulness thereof, and the method of construction whereby inexpensive materials may be utilized.

\Vhile the broom described herein is well adapted to accomplish the objects of thea side elevation of a broom embodying the present invention. Fig. 2 is a mid-sectional view of the same. Fig. 3 is a detail view of the reinforcing means. Fig. 4 is a side elevation of a modified form of broom, showing side plate reinforcement upon the exterior of the'brush elements. Fig. 5 is a transverse sectional view of the broom shown in Fig. 4. Fig. 6 is a transverse sectional view of the broom shown in Fig. 1. Fig. 7 is a side view of the brush elements before attachment to the reinforcing means.

Assuming the invention to be embodied as shown, my improved broom consists of a handle 11, provided with a slot 12 adjacent to the bottom end 13, and provided with an angularly disposed bar 14, serving as a reinforcement for the brush filaments 15, which are preferably made from palm fiber, or any inexpensive material coarser and stronger than broom corn, the palm fiber being cheaper than the broom corn. Parallel reinforcing strips 16 and 17 are mounted beneath the bar 14, and the inner brush filaments 15 are clamped between strip 16 and outer strips 17. The brush filaments 15 are secured at the upper end to the handle 11, being clamped with the binding wire 18.

Specification of Letters Patent.

Serial No. 278,714.

The side or edge reinforcing members 19 are secured to the handle 11 and to bar 14, and are provided with notches 20. The handle has secured thereto the cloth fabric shields 21 and 22-. which serve as protectors for the upper ends of the outer broom corn fibers 23, surrounding and incasing the innerpalm fibers 15. Binding elements 24 are stitched through the outer and inner layers of brush filaments, some of the binding elements passing through slot 12 in the handle. Binding elements 25 are stitched through both layers of brush filaments, some of them being above and some below the strips 16 and 17, and some of the binding elements engaging with notches 20, which prevents displacement of the brush elements relative to the reinforcing members 19.

In the form shown in Fig. 4 and Fig. 5, thin reinforcing plates 26, preferably of wood material, are provided, and binding cords 27 are stitched through the brush filaments and to the reinforcing plates.

The several reinforcing means herein set forth, are well adapted to serve the purposes intended, tending to preserve'the original form of the broom and prolonging the term of usefulness thereof.

In constructing the broom, the handle 11., bar 14, and edge strips 19, are first assembled, being secured with fine nails at the points of juncture. The assembled handle and reinforcements are shown in Fig. 3. The inner brush filaments 15 are then secured between clamping strips 16 and 17 as shown in Fig. 7. Thebrush is then secured to the skeleton frame, and the outside layer of finer filaments 23 are applied, allowing the inner brush filaments 15 to project below the filaments 23. The whole is then secured by the binding cords 25 which are stitched through in the usual manner.

The plates 26 are secured by the binding cords 27, the plates lying on the exterior of the outer layer of filaments, and serve to strengthen and add stiffness to the brush filaments of the broom.

, From the foregoing it may be seen that I have produced a broom simple in construction, inexpensive to manufacture, adapted for longer service than the ordinary broom,

and adapted to retain the original form during the use thereof.

What is claimed is: A broom embodying a handle, a bar at 5 the extremity thereof, a fiber core incasing the bar and secured to the handle, brush fibers incasing the core reinforcing plates disposed on opposite sides of the broom, and flexible binding cords stitched to the brush fibers and reinforcing plates and passing 10 through the fiber core.

In testimony whereof, I have hereunto affixed my signature.
